FILLINGMACHINE Specification of Letters Patent.v

Application filed April 21, 1917. Serial N0.'1$3,603.

To all whom t may concern.'

Be it known that I, KARL KIEFER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Filling-Machines, of which the following is a specification.`

My invention relates to filling apparatus, and more especially to that kind of apparatus used for filling vessels or containers with substances wh1ch do not flow readily, but are rather of a semi-fluid or viscous consistency.

The object of my invention is to ll vessels or containers with such substances rapidly and uniformly Without waste, deterioration or contamination of the substance;

In the drawing:

Fig. 2 is a longitudinal vertical section on a plane coincident with the center lines of the carrier sprockets;

perspective view of a Fig. 8 is a vertical cross section on a plane corresponding to the line 8-8 of Fig. 7.

As I prefer to construct my invention, there is a base 1 supporting a table 2. This talble has an opening 3 (Fig. 2) and a bearing hub 4 has a flange ibolted down to the top of the table and extends 'some distance above this flange and also extends below the flange through the opening 3. The main shaft 6 is journaled upright in its bearing hufb 4; extending to a considerable distance above the upper end of the hub 4 and being provided with a longitudinal key way 7, as well as with a coarse thread S, and has the driving sprocket wheel 9, to be referred to later, keyed on it and supporting it on lthe hub- 4.

This threaded upward extension of the main shaft carries the filling head, which,

comprises the distributing head 10, which, as here shown, is made up of a flat sevensided body with a central externally-threaded neck 11 extending up from the body with its interior openingcontinuous and smooth through the body and slidably receiving in its interior said upward extension of the shaft 6 with a suitable spline 12(Fig. 4) sliding in the key way 7. Below this distributing head a suitable hand Wheel 13 travels on the threads 8 and supports the filling head. rlhus the distributing head 10 may be adjusted up and down in the shaft 6, but it will always turn with the shaft. The upper side of the distributing head kbody is made very flat and smooth, and discharge passa-ges or orifices 1'4 are provided therein, each one of these opening from the upper flat surface and leading down and then radially outward through a respective one of the seven sides of the body. As shown in Figsiy 1 to 4, inclusive, spoutsl are bolted to the respective sides, each with its interior passage or orifice forminga continuation of a respective discharge orifice or passage 14; these spouts being directed downward with their lower openings all in a single circle concentric with the shaft 6. The openings of the discharge orifice or passages intheflat top are also arranged in a single circle concentric with said shaft and preferably in an annular gasket section 16 of soft metal lsuch as Balbbitt metal.

Fitting down along the neck 11 is a. controlling head 17 which has a flat lower surface adapted to fitthe hat upper surface of the distributin head 10 very accurately, and with a circuin erentially elongated delivery passageor orifice 18 opening through it in such position that each discharge passage or orifice 14 opening through the' upper surface of the distributing head, thus closelyv contacting with the lower surface of the controlling head, will register with this delivery passage or orifice 18 during relative rotation of the heads. The controlling head has an vupstandinghub 19 where it lits around the neck 11 and on top of this hub is a washer 20 screwed down against which is a nut 21 which in turn has a lock nut 22 screwed down against it on the externally threaded neck 11. By this `ineans the controlling head is'clamped as tightly as may be desired against the distributing head,

Patented Aug. 19, 1919.

with the result that leakage from the de- 4livery orifice 18 out lbetween the heads is minimized; this eect being greatly augmented by providing the soft gasket section 16 before alluded to, and making the controlling head of a good non-corrosive metal, such as bronze.

It being necessary to lubricate the bearing of the controller 17 around the neck 11 vand yet to keep the lubricant out of the delivery and discharge orifices, as well as keep the filled substance out of the bearing, I prefer to provide the distributing head body with drain openings 2,3.down through it radially inward from the gasket section 16, all connccted by an annular groove 2d (F ig. 4) which will thus intercept any slight amount of either substance and allow it to pass down below the filling head where it can do no material harm. Such a device is according to my Patent No. 1,022,196 of April 2, 1 912. As the distributing head rotates, it 1s necessary to hold the controlling head stationary; but as both are clamped together and must be adjusted u i and down on the shaft 6, the controlling iiead is simply proe vided with a radially outwardly extending spur which engages with a high stud 26 fixed in the table 2 -some distance away from the shaft 6,

As hereinbefore alluded to, my present in vention is especially for filling'substances that do not flow readily, either under the ac tion of gravity or pressure of the atmosphere. Therefore, this machine is provided with means for uniformly forcing the sub stance out through the orifice 18 to the successively registering discharging orifices. For this purpose l prefer to employ as a forcing means a spiral gear pump 27, such as disclosed in my Patent No. 1,103,053 of July 14, 1914, which com rises an outer casing 28 inclosing a coup e of intermeshing spiral gears 29 and 30 (F ig. 1); the casing being bolted to the side of' a suitable bracket- 31 mounted on the base 1 under thetable 2 at the right. The upper side of the pump casing 28 has a large opening 32 which it will be understood may be provided with a hopper or preferably with a pipe communicating with a suitable s ource of supply of the substance to be filled; and from the lower side of the pump casing 28 leads the conducting pipe 33 which passes in over the base 1 and up through the table 2 (Fig. 2) almost to the height ofthe main shaft 6. Since the filling head must be adjusted 'up and down,and this conducting pipe must connect with the delivery orifices 18 in the filling head, the upper end of the pipe 33 communicates with one end of a fiexible section of conductor 34, the other end of which is connected with an upwardly extending neck around the delivery orifice 18 in the filling head; said flexible section 34 being long enough' to permit the up and down adjustment of the filling head without'interfering with the communication through the conductor.

The main shaft 6 has an extension below ,erase the bearing huh d, on which is fixed. a worin wheel 35 surrounded by a gear box 36 which is fixed on the lower end of the bearing hub. A worm 37 is fixed on a worm shaft 38, extending from the front to the rear of the machine,'with bearings in the gearbox 36, and having, where it extends out to the rear of the machine, a pulley 39 fixed on it (Fig. 1) which may be belted to any suitable motive apparatus such as an electric motor, by means of which the entire machine is driven.

lt will be seen that by the worm wheel, the main shaft 6 will be rotated and with it the distributing head 1 0, as above described.

For driving the gear pump simultaneously with the operation of" the filling head, the worm shaft 38 has, where it extends toward the front of the machine, a friction wheel 40 splined on it and bearing down against the plane upper surface of a friction disk 41 fixed on an upright shaft d2 that is journaled in a suitable bracket t3 mounted on the rear side of a pedestal 44, which in turn is mounted on the base 1 near the front of' the machine under the table 2; said upright shaft 42 having fixed on its lower end a bevel pinion 45 in mesh with a bevel gear i-6 fixed on a horizontal shaft journaled in the lower part of the bracket 4:3, and having fixed on it, to the rear of the bracket, a sprocket wheel 4'?, around which passes a sprocket chain 48, 'which also passes around a sprocket wheel 49 fixed on the outwardly extending shaft 50 of the gear 29 of the gear pump 27.

The friction wheel 40 is between the downwardly extending members of a yoke 51 which travels on a horizontal screw 52 journaled in a. bearing 52 Fig. l) mounted on the top of the pedestal 44; said screw having fixed on it, out in front of the table 2, a hand wheel 53 for turning it. Thus the friction wheel 40- may be adjusted nearer to or farther from the center of the friction disk 41, so that with a given speed of the motive apparatus and of the main shaft and filling head, the pump 27 may be driven slower or faster. This causes what may be called a fine adjustment of the speed of' the pump relative to that of the filling head to determine the exact amount to be putl into each container. For greater changes. in this relative speed, smaller or larger"y sprocket wheels may be provided in place of the sprocket wheel d'7, and the sprocket chain is adjusted to these diderent sprocket wheels by an idlerwheel 54 journaled loosely on a stud 55 that is adjustable up and down in a stirrup 56 fixed on the top of the base 1 under the table 2, as is clearly shown in Fig. 2,.

F or carrying the vessels or containers into receiving relation with respective ones of the spouts 15 of the filling head, I prefer to provide an endless system of carriers 57, all mounted on a sprocket chain 58 that passes around the sprocket wheel 9 keyed on the vverse plane z'.

main shaft 6, as before described, and around an idler sprocket wheel 59 supported as will presently be described. The. containers are thus brought to the spouts in a transe., a plane lying across the machine parallel with the plane of the 'spouts, as is desirable for accuracy and avoidance of spilling and waste.

Extending to the right, with their center lines tangent to the pitch circle of the sprocket wheel 9, at front and rear thereof, are troughs 60, each composed of a bottom bar 61 and flanking guide rails 69. bolted thereto said bottom bar 61 being secured to pedestals 63 that extend up from the top of the table`2, and which table preferably extends somewhat to the right to support the outermost two of these pedestals 63. A. U- shaped outer guide rail 641 has its side parts bolted to the respective outer guide rails 62 of the troughs 60 and extends around the sprocket wheel 9. At the right hand ends of the troughs 60 is the bracket 65 bolted to the under sides of the trough and having a slot 66 extending from left to right and opening upwardly and downwardly, in which is bolted the upright stud 67 with the idler sprocket wheel 59 loosely journaled thereon above the bracket 65. By adjusting this stud 67 inwardor outward along this slot 66, the tension onv the sp rocket chain 58 may be regulated. A suitale guard 68 has its bottom around the stud 67 under the idlers rocket 59 with its rim extending outside t e adjacent ends of the troughs 60 as is best seen in Fig. 2.

The chain 58 is Yan ordinary detachable link sprocket chain and the sprocket wheels 9 and 59 are made to fit it, each sprocket wheel having seven teeth, which is the reason for making the distributing head 10 with seven sides, because it is the pur ose to have the carriers 57 come between adjacent teeth of the sprocket wheels and to have these carriers under respective spouts 15 of the distributing head as they travel the semicircular path at the left of the center line of the main shaft 6. As designed, only every third link of the chain meshes with a sprocket wheel tooth and the sprocket wheels are cut away between their teeth, as shown at the extreme left and right in Fig. 2, thereby leaving a space for overlapping connection of the chain links that are between the links that are meshed with the adjacent teeth.

Between the sprocket wheels, the lower sides of the chain links slide along onthe top of the bottom bar 61 of the trough 60 and are thus supported thereby.

Each carrier 57 has downwardly extending lugs 69, each of hollow substantially semicylindrical cross-section, with their concave sides toward each other and ianked by wings 70. The substantially cylindrical` space defined by these concavities receives the hook 71 of one link with the cross bar 7 2 of the neXt link engaged therein, while the wings 7 0 at respective sides of the lugs 69 closely flank the longitudinal bars 73 of the respective links, as is best seen in Fig. 5. On the middle of the outer convex part of each lug 70 is a rib 7l: to bear out against the inner side of the adjacent guide rail 62, and on th'e underside of the carrier 57 are ribs to bear down on the top of the outer guide rail, and a rib 76 to bear in like manner on the inner guide rail 62, thus slidably supporting the carrier, so that as it is drawn along by the chain it is kept in upright position at all times. As the carrier passes around either one of the sprocket wheels, its inner rib 76 side of the rim 77 of the sprocket wheel and `its outer ribs 75 bear on the upper edge of the U-shaped guide rail 64er of the guard 68, as thecase may be.

1t will thus be seen that each carrier 57 is very securely mounted on the chain 58, and at the same time, is readily detachable therefrom at any time for the substitution of4 a carrier'of different vshape or size or for any other reason. This mounting of the carrier on the chain practically prevents articulation of the two links engaged, but this is no detriment, because the next link in either direction has its full freedom of movement with respect to these two and the chain thus readily passes around the sprocket wheels. As here shown, the carrier`57 itselfcomprises a 'lat'bottom 57 with an upstanding rim 57" at the sides and rear, which latter is substantially semicircular, and the front edge of the bottom 57 is left free for the ready placing and removal of the containers. 1t will be understood, however, thatthese Carriers may be of any convenient shape.

lll/'here the container is of a diameter to tit fairly closely between the sides and against the back of the rim 57, the containers will be centered with respect to the spout-s 15 by this means.

However, in order to provide for the centering of containers of various sizes, 1

bears on the upper prefer to provide a series of gages 78 mountalong the top of the disk 79 parallel to a radius through the junction of the arms 80, which shank is bolted to the disk 79 by a bolt 82 passing down through its slot as by the means well as held from lateral a dowel pin 88 in lthe top of the disk 79 and engaging in said slot. T his slotted shank is disposed away from the radius 'far enough to allow its inner end to pass to one side of the main shaft 6, thus giving greater range of inward or outward adjustment of the gage.

To cause containers 'to move in between the diverging arms 80 as they start around their semi-circular path, a 'Iiat spring Si has one end lined on an upwardly projecting stem 85 on the table 2 to the left oi said path and extending to the right therealong, and presenting one of its dat sides inward and preferably being suitably curved to allow the approaching container to slide readily inside the spring 811 and be pushed into position between the arms 80, dueto the resiliency of the spring 84, which position the container will then keep during the remainder of its travel, in receiving relation with the respective spout l5 over the carrier 57 that the container1 is on. lt will be seen that the radial adjustment oi the cages 7 8 permits them to center containers of various diameters or shapes, and it will also be understood that gages of different shapes may be substituted in accordance with the requirements in handling containers of diterent shapes.

A great many of the containers in which substances are placed by this machine have wide mouths; hutit is also frequently dedisplacement by sirable to use containers with comparatively narrow mouths or necks, as, for instance, ordinary bottles. Also such containers of the saine lot are liable to vary in the shapes of their bottoms or of their necks, so that the centering of the body of the container just described, or any equivalent means, is not suihcient to insure just the proper relation of the mouth of the container to the respective spout l5.

For overcoming this ditliculty l prefer to provide a mouth-centering attachment 86, as shown in Fig. 8, which comprises a hub 87 split at one side to slip upon and be clamped to the spout l5 by a screw 88 passing through ears 89 at opposite sides of the split of the hub and, extending downwardly from this hub 87, a semi-circular rear wall 90 "from which lips 91 diverge forwardly. Thus the attachment has a wide opening in front to receive the container top or neck, so that when used in conjunction with 'the spring 8a or equivalent means, the container will be forced inward so that its top or neck lits snugly inside the concavity of the semicircular rear wall 90, which is ina-de concentric with the spout opening and of the proper radius to produce this eect with any given container; it being understood that dierent size-d attachments may be put on for containers with materially different or ori Laia-soi sized tops or necks. lt will also be understood thaty this attachment be used in conjunction with the gages 78, since the spring 8l will press the bodies ci the containers against the gages and also press the tops of the containers over against the attachment 86.

rom the foregoing description it will be understood that the pump 27, driven simultaneously with the driving of the main shaft 6 which actuates both the iilling head and the carriers, will deliver the substance to the filling head at any uniform rate, according to the adjustment ci' the friction wheel el) and the size of the sprocket wheel el?, withY the result that the containers brought around at equal intervals will receive through the discharge orilices, registering' with the delivery orices at the same equal. intervals, equal quantities of the substance. This is a greatly desired result in most instances.

However, as before alluded to, containers, especially those made of glass or the like, vary in shape so that vwhen an equal quantity of substance is put in each one ot :the containers of a given lot, the substance reaches a higher level in some than in others. Thus, while the containers have equal quantities of substance, they do not appear alike, and this lack of uniformity in appearance is regarded by some users as less desirable than a lack of uniformity of substance. Therefore, l have provided a modification of my invention which will insure that the containers will all be turned out with the sub-v stance at uniform height, even though their contents vary slightly.

This modification is shown .in Figs. 7 and l8, it beingunderstood that it all resides in the i'illing head, the other parts of the inachine being as shown in the preceding iigures and as has been described. Thus, there is the main shaft 6 with the. hand wheel 13 'threaded thereon, supporti the distributing head 10, which, except or the different location ol the bolts which hold, on the respective ones oi the seven sides, attachments in place oit/the spouts l5, isthe saine as in the preceding example. The controlling head 17', however, has, in addition tothe delivery assage or orilice 18, a suction passage lice 9:2 spaced a suitable hdistance around from but being in every way like the discharge passage or orifice 18.

n From this suction passage or oriiice 92 a suitable conductor 93 leads to a suitable suction-creating apparatus 94 (only shown diagrammatically in Fig. 8.)

This controlling head also has columns 95 which support the calin 96 made up of upright annular shell at the bottom of which is an inwardlr extending annular lla-nge by which it is colt/ed to the columns '95 concentric with the .main shaft 6. .ln the outer surface oit its annular shell this lll) cam 96 has a groove 97 which runs around at a uniform height, except for a short distance on either side of the suc-tion orifice or passage 92, Where it has a louI part 98 with suitable inclined parts leading to and from it; it being understood that it is the suitable inclination of these parts that governs the angular distance of the suction passage from the discharge passage. The spur 25 is here mounted on the top of this cam 96 and it will be understood that the stud 26 will be extended up accordingly. y

Instead of the spouts 15, each of the seven sides of the distributing head has mounted on itv an attachment comprising a body 99 with va passage or orifice 100 forming a continuation of the respective discharge orifice of the Ydistributing head and opening outwardly into an upright groove 101 in Which a spout-head 102 slides up and down With a recess 103 in its inner side and a spout 104.

`leading down from the bottom of said recess 108 to discharge the substance into the container. A suitable resilient holder 105 presses the spout head 102 against the inner side of the groove 101 at all times, yetallowing Vsaid head to slide freely. 1n the-inner side of the upper part of the spout head 104 is fixed a pin 106 that extends into the slot 97 of the cam 96.

With this construction, When the distribut? ing head 10 rotates along with the main shaft 6, and the controlling head 17 is held stationary, the spout-heads 102, With their spouts 104, will be held up by the pin 106 riding in the uniformly high part of the groove 97. But after they pass the delivery passage v1S they will be forced down on account of the pin 106 passing into the lo\v part 98 of the groove 97, so that the spout 104L will be projected down into the substance that has just been dischar ed into the container, and when the disc arge passage 14 registers with the suction passage 92,.the suction-creating apparatus 94 Will draw the substance out of the container downfto the level of the spouts 104. The filling head having been adjusted to the proper height on the main shaft 6 to bring the lower ends of its spoufts 104 to the desired level, it will be scen that all containers will thus be left with substance to the same level. rEhe recesses 103 in the spout-heads 102 are made long enough to communicate with the continuous passages 100 and 14 at all times, Whether the spout-head and spout are raised or lowered. As the hub continues to revolve, the spout-head and spoutI will of course be raised again into the uniformly high part of the. groove 97, permitting the container to pass, with the carrier 57, off at a tangent io the semi-circular path that it has been traveling; and it will be understood that the suction passage will be so located that the spout will be entirely out of the container before the latter'can begin its travel at a tangent. A diverting guide bar 107 (Fig. 1) preferably has one end fixed to the stud 26 and extends to the rear over the carriers 57 at a proper angle .to divert the 7o containers off their carriers onto a table or anylother receiving means, notI herein shown. aving fully described my invention,
